The UK border force is making arrival into the UK (even as a UK / EEA national) an unnecessary pain.
By all means control the border but do it, as it was done previously, before the idiot Theresa May found out - that is by officers using their intelligence to target the people they need to question in greater detail.
Meticulously checking everyone's passport is largely unnecessary, and creates irritation for visitors and UK citizens returning to the UK alike - just look at the Stansted thread in "Airlines, Airports & Routes" to see that. The current system does little to enhance the UK's appeal as a tourist destination.
Of course, we could just join Schengen - but that ain't about to happen.
